OpenSUSE Network :: Cannot Resolve Host Names On Local Network?
Mar 9, 2010
I have a mac and an openSUSE box connected wirelessly to a router. From my mac, if I ping the Linux machine by both ip address and hostname "elmo.local", I get a response. If I ping my mac from the Linux machine using its ip address, I get a response. However, if I ping the mac from the Linux box using its name "kermit.local" - nothing!
This means in order to share files between them via the network, I have to use the ip address rather than name, but I'd rather not. When I had Ubuntu installed instead of openSUSE this all worked fine out of the box, so I'm assuming it's a problem with the setup of openSUSE rather than the router or the mac.
I have three Debian systems running, along with several XP laptops, PS3 and two DirecTV systems. I use two of the three Debian systems as media servers, and the third is an older system mostly for playing around with. My home network is running fine with the following nuisance. The two newer Debian (Lenny) systems are <barney> and <mitzi>, the older is named <oscar>, running Debian Sarge 3.1. From either locally or remote login to <barney> and <mitzi> I can ssh into either of the other two systems, however when logged into <oscar> I cannot ssh by name to either of the other systems. e.g. ssh: mitzi: Temporary failure in name resolution..However, from <oscar> I can ping outside my network (e.g. ping www.google.com) with no problems.I can also ssh to the other systems via IP address, just not by name.
I've compared the /etc/ssh/ssh_config, /etc/resolv.conf, /etc/ssh/sshd_config and other files between the two systems and not seeing anything peculiar. arp, route, etc., don't show different behavior between the systems either.
I'll apologize in advance for I'm sure this has been covered already, but I'm not sure of the search terms to even use to begin solving this problem. I don't know what I don't know.
I have three computers on my home network and want to reach them by their name instead of IP address since their ip is dynamically assigned. I'm using a Linksys WRT54GL router and have noticed that there exists a "DHCP Clients Table" in the router that seems to hold all the necessary information - host names and ip addresses.
How can I get my computers to use that as the lookup table to resolve the host names? And is this even an optimal way of being able to resolve local names?
I'm running openSUSE 11.2 (Linux piura 2.6.31.12-0.2-desktop #1 SMP PREEMPT 2010-03-16 21:25:39 +0100 x86_64 x86_64 x86_64 GNU/Linux) and have a network problem. At work, ethernet works fine. When I plug it into my DSL router at home (which works with other computers), I encounter the following behavior: ping can resolve host names, however, traceroute and Firefox and Thunderbird cannot. It happens for both wired and wireless connections.
How do you get linux to resolve local hostnames without DNS?
I've recently migrated from a fully windows home network, to a few linux machines and im unable to ping any local machines with hostname via these linux machines. i can ping IP and internet hostnames. also, windows > anything pings ok too. however linux > anything will not ping via hostname.
I beleive it's an additional service running on windows to resolve hostnames without DNS (wins/netbios).
DNS is done via a netgear DG834 router (DNS forwarding).
I know i could either use direct IP, or add machines into the hosts file, but im wondering if theres some way around that and to have it dynamically update like it does on the windows machines. static mappings seem a bit silly inside DHCP zones
I've seen some reports of avahi causing local network issues (taking over the .local domain), but i think this only extends to having to manually enter in .local after the hostname and even after removing avahi, the problem is still present.
In short: browsing the internet with domain names does not work. The long version: I've configured my network with DHCP and ifup. Ping works on my internal net and with servers in the internet. Dig work's too! I get the right IP to the requested domain. When i try to access the internet using firefox or even wget i get an DNS error. For example wget is showing the following error: Resolving heise.de... failed: Name or service not known. wget: unable to resolve host address 'heise.de'
Again dig show me the right IP and if i add the entry to /etc/hosts it work's too! I've even tried it with manually setup of ip address, nameserver and default gateway but with the same result. Switching off the firewall has no effect on this problem, too.
We are in the process for Integration Network with our Government Network. Let say that our network are 192.168.0.0/24 And the Government network are 10.0.0.0/8 I want to know if the local network can resolve the internet names in Government Network. I am using Bind for DNS.
I have two machines on my local netowrk, one running Fedora 9 and the other Fedora 11,(64 bit version).I made one, machine A, into an NSF server and arranged to export a directory to the other machine B.I made sure the firewalls were allowing nsf traffic, and I restarted all the relevant daemons.But the mounting still doesn't work.I looked at the setup on my Linksys router, but I don't see anything obvious there that might be getting in the way.ping and ssh recognize my names for the two machines and work properly, bu t I've also tried using the numeric local ip addresses.I tried with the program showmount on B to see if there was any connectivity and I getB% showmount -e Aand I get the responseclint_create:RPC: Port mapper failure - RPC: unable to receive.I used to manage a departmental network and set up nfs mounts all the time, but things were simpler then. I am at a lost what to look at next
I just installed opensuse 11.4 and i'm not being able to connect to my wireless lan. It recognizes my network, but when I click "ok" after typing the password it is like I had done nothing, no connection is set at all.I guess it is probably some configuration stuff since my notebook recognizes all available wireless networks. Sorry about the lack of details, but that is all I got.
I recently installed bind9 on mandriva 2008.1, after having done the necessary configuration.. I still can't find my domain I configured cant ping on other machines on the LAN but can actually ping on any other website on the internet even though name server is configured to point to local machine..... I dont understand what I'm doing wrong.
I just installed open Suse 11.3, and I cannot SSH my school. Upon further investigation I could not even ping any machines outside my local area network. Ironically I could nmap machines outside my local area network.
Does anyone know how to permanently enable X connections from all machines on my local network. I keep having to enter 'xhost +' to allow X connections.
I am trying to host a local website(an wiki application) within a network. Is it necessary that all the files I need to upload should be in the var/www?
I just intalled OpenSuse 11.2 on VmWare Server 2.0.2, the network is configured as Bridged and is sucefully configured a fixed IP in my network. Ok... The problem is... I can ping / trace all addresses from OpenSuse console. But I Can't wget all of them... It's a random thing. the same address that trace's ok, don't work for HTTP.
I want to use single label host names on my local LAN, without using any domain (at least no registered one). My machines should be named in a fashion similar to 'myserver', 'mydesktop' etc. so that i from a browser on any LAN machine may write 'http://myserver', and get the webserver on 'myserver' (so NO domain part, e.g. myserver.domain).
Do i need to create a DNS zone for each host or is there a way to put all host in a single zone, if so; which? Would such a name be considered a root domain?
I have just loaded Suse 11.4 and have had (2) problems, 1st: When I installed some additional programs, such as, Scribus, the system showed them as installed but they did not show up in the "applications" menu any where. I finally tracked them down and edited them in and they work fine - Why aren't they being automatically placed into the menu system? 2nd: I have a home network setup and all systems can see and work with each other, however, the host system is not shown as if it did not exist at all. for example; if I go to "network services" and select "Samba Shares" if other computers are connected it will show them but not the host - if no other computers are connected it shows nothing. On my 11.3 system it shows the host eg; "Linux-12fx blah blah" this is of course my host machine. I have replicated all of my settings on the 11.3 settings on my 11.4 system - no luck!
I have an internal domain (dev.lan) for which my Ubuntu server is authoritative. We have a number of subdomains under that domain (test.dev.lan, svn.dev.lan, etc.). The server also acts as the primary DNS server for my office. It was originally set up under Ubuntu 8 and worked great.
However, ever since we upgraded to Ubuntu 10, our Windows clients periodically lose the ability to resolve domains on the dev.lan domain. Internal IP addresses can still be pinged from the Windows machines so it does not appear to be a network-connectivity issue. External domain names continue to resolve without any problems. The only workaround is to restart networking on the Windows clients. It's frustrating because it happens several times a day.
dammit... all that typing and I hit the wrong "submit" button. *sigh*
Ok, I have a couple of SMTP servers for our infrastructure. They are running Postfix. I have them configured so that specific email addresses such as support@mydomain.com and billing@mydomain.com all go to a new support server that I am building with osTicket. Lets call that server SUPP1.
SUPP1 runs sendmail from the default install of CentOS 5 i386. At this point everything runs great. New emails get added into the osTicket system via a pipe in sendmail. Here's where the problem comes in. In order to accept mail, sendmail has to have the domain listed in local-host-names and the addresses in virtusertable. That works just dandy. But in doing so, sendmail believes it is the destination SMTP server for "mydomain.com". That means that I can't send mail from that server back into my normal SMTP servers. So things like the LogWatch, cron jobs, etc can't send notifications. Is there a way to work around that? For sendmail to ignore local-host-names for outbound email or something?
I made a script to backup file from each host with general password in local network. This script using SSH Pass and Rsync with this
syntax: rsync --rsh="sshpass -p password ssh -l root" hostath destinationpath Everything is okay under 9.10 version until I migrate to Ubuntu 11.04, there is always give an error: rsync error: received SIGINT, SIGTERM, or SIGHUP (code 20) at rsync.c(541) [Receiver=3.0.7]
I am using bash version: GNU bash, version 4.2.8(1)-release (i686-pc-linux-gnu) and 2.6.38-8-generic kernel
EDIT: Thread name should be "No network on XEN guest ofcourse". I am trying to run OpenSUSE 11.3 as guest in OpenSUSE 11.2 as host. First problem I came across was libvirtd service wasnt started and after that I was able to install guest OS. Now there is a problem as guest doesnt have connection with internet. Here is the script for the guest
I have installed WICD on Debian . I can now access a new a Network Manager screen, which did not exist before, but it does not display/detect any wireless networks. It is like dead. Before installing WICD I did at least have a wireless WPE encrypted network, which was detected, although it often disconnected for no known reasons. Now even that Network has gone and I can't go on line. Can anybody help here? How can I configure the WICDNetwork Manager to detect an existing network or create a new one? In the latter case, would I have to reconfigure the Router settings to setup/connect to a network in Debian? May be I have to do this, because Tor/Vidalia changes my IP address and so my Network Adapter ( Linksys) can no longer connect to the router. Also, when trying to follow troubleshooting leads in this connection, the Terminal screen on Debian ( CMD) would often return a PERMISSIONS DENIED message.
here are the steps that i have taken already to resolve and troubleshoot the issue. i can ping Google. i can browse the Internet i can browser the repo Index of / through my browser. i have insured that ipv6 is disabled through network configuration through yast.
I'm able to connect to my company's VPN network using GNOME NetworkManager but when I try to login to the remote system using SSH it is not able to resolve the DNS name, It works fine if I use IP instead of the FQDN.
I'm not sure what I did if anything but I have not used my opensuse for several months. Now when I try to connect to the Internet I can not pull any websites. The wireless connection is active and connected. I am getting an IP address via dhcp. When I try and ping out (opensuse.org) I get unknown host. If I ping an IP address or type the IP in my browser it works fine. nslookup works but only if I specify the dns server.
Here is a copy of my troubleshooting commands.code...
Just recently installed Opensuse 11.2 in a KDE environment. The problem I am facing is that when I connect it to my network either via wired or wirless neither getting internet or access to the network although the network manager shows the connection as active I am using a Dlink Di-524 Wireless Router at home The Wirless router for the computer is Broadcom BCM 4312 Was able to install the drivers for this from the packman repository
Also when I connect my laptop directly to the internet connection via wired it is working fine. However if i connect it to my wireless router either over wifi or thru wired it just shows connected but i can neither access internet or other computers on the network. Have checked the wireless router other computers (windows and ubuntu are being able to access the internet via it) Results of my ifconfig-a command when i am connected over my wirless connection code...
I installed 11.4 from a verified and checked CD. Had and worked through the DSL and ipv6 problems discussed elsewhere in this forum. So browsers now work on the internet, but neither zypper nor yast will resolve the 11.4 repositories, so no refresh, no updates. Browsers bring up the repositories fine, so I can download and install an rpm that way, but it's not a life. Haven't been able to find this issue elsewhere, asis usually the case.
When I set my DNS servers via Yast>Network Devices>Network Settings>Hostname DNS it accepts the addresses, but then when I check then the next time they are faded out. I set them again, but same results.
today I tried to configure a network route to a host for testing my network interface. Code: route add 192.168.1.15 eth0 As I have to eth interfaces and both interface got their IP from DHCP (192.168.1.11 and 192.168.1.12) and are in the same subnet, I shut the other interface down:
Code: ifconfig eth1 down Then I tried to test the interface by doing a ping to 192.168.1.15. Problem: When I unplug the cable from eth0 (and eth1 is still plugged) the ping still works. Somehow my linux (it's debian) powers up again eth0 and pings over this port.
How can I stop my linux doing this. I just want to have the route added only on the one interface - not the other. Is it maybe some case of a default-gateway?
I'm working with a Ubuntu 10.04 LTS system with two network interfaces (both Ethernet). I wish to setup this system such that it is simultaneously connected to my local and an OpenVPN network and able direct traffic between the connections depending on what program is sending the traffic. The problem: Under my current OpenVPN configuration all network traffic is directed to the VPN.
In practice, I would like OpenVPN to operate out of one of my two network interfaces and leave the other interface connected to the local network. Then by default all network traffic should be directed to my local network unless I specify (on a per program bases) that certain traffic should go though the VPN. These two network connections can (should) stay completely independent of each other and do not need to talk to each other.
